Title: Power source for electric discharge machining
Inventor: SUZUKI TOSHIO
IPC: B23H1/02
Filed: 1985-05-15
Abstract: PURPOSE:To obtain a large output range while maintaining a stable output characteristic and obtain a good-quality and uniform machining surface by providing a coupling capacitor and a coupling coil in series in a circuit, and plural capacitors and their switching means in parallel in part across poles, and switching he values of said capacitors in a proper range. CONSTITUTION:When the on and off operation, at a few MHz, of a switching element 2 is repeated by means of a driving circuit 3, a voltage on both ends of capacitors C2, C3, i.e., a high-frequency AC voltage, is generated across poles 6, to carry out electric discharge machining. The characteristic of the output voltage with respect to variation in floating capacitance 8 depends on the capacitance of a coupling capacitor 9 and the inductance of a coupling coil 10. Also, by selecting the value of a capacitor 11, the output voltage can be greatly stabilized with respect to the variation in the floating capacitance. And, further, by switching the capacitor 11 in a proper range with a relay 12, an output characteristic can be stabilized, obtaining a good-quality and uniform machining surface with a wide range of machining application.

IPC: B41J2/44
Filed: 1984-05-18
Abstract: PURPOSE:To make a recording object easy to visible by setting a density of a non-picture part of a negative film to the maximum density or above, and recording it. CONSTITUTION:A synchronization is applied to the output (f) of a clock generator 31 by the output (a) of a photodetector for detecting a width in the main scanning direction of a recording medium. This clock (g) is counted by a main scan counter 33, and becomes position information in the main scan direction. A sub-scan counter 34 counts the output (a) and generates position information in the sub-scanning direction. An area setting circuit 35 receives the position information of the counters 33, 34, and generates various signals. In a picture part area, signals (b), (c) are sent to a read-out address counter 37, and a picture is read out of a picture memory 36. At the time of a non-picture area, a signal by which an output of an OR circuit 38 always goes to ''1'' is generated, the density of the output goes to maximum.

IPC: G11B19/04
Filed: 1987-04-27
Abstract: PURPOSE:To execute the highly accurate real time lifetime detection for a magnetic disk by monitoring a threshold voltage for detecting a sudden oscillating component and a frequency converted by a voltage comparator at all time. CONSTITUTION:An elastic wave detecting sensor 1 detects an elastic wave that occurs because of the sliding friction between a magnetic head and a magnetic disk medium. Thus detected elastic wave is compared with a threshold voltage by a voltage comparators 5a, 5b, and converted to frequency signals corresponding to the wave. These frequency waves are always inputted to threshold voltage servo circuits 10a, 10b, so that a threshold voltage for the comparators 5a, 5b is automatically set to come equal to a voltage level for the sudden oscillating component detection of the magnetic disk medium. And the threshold voltage for detecting the sudden oscillating component which is distinct at the end of the lifetime of the magnetic disk medium as well as the frequencies converted by the comparators 5a, 5b are always monitored. In such a way, the highly accurate real time detection of the lifetime of the magnetic disk is executed.

Title: Data collecting system
Inventor: FUKUDA SHUICHI
IPC: H04Q9/00
Filed: 1987-04-24
Abstract: PURPOSE:To collect only data received from parts to be controlled at a high speed by decoding address information signals received from each part to be controlled via a control part. CONSTITUTION:Respective parts A1-An to be controlled output signals showing the presence of transmission data to their own time slots allocated to a response data line 5 as long as the parts A1-An have data to be sent to a control part 1. The part 1 always monitors the lines 5 sent from each part to be controlled via an address/data detecting circuit C. If an address information signal is produced on the line 5 sent from a part AX, the part 1 detects the address information signal received from a part to be controlled via the circuit C and outputs a data collecting signal including a prescribed address signal to the part AX via a control line 4. Thus the part AX having a prescribed address equal to the address outputted from the part 1 sends back a response signal via the line 5 in a frame following the data collecting signal.
